HAB - Evaluation of heroin-assisted treatment

We will evaluate a new heroin-assisted treatment (HAB) pilot project in Oslo and Bergen, Norway. Our goal is to provide a recommendation as to whether HAB should be continued, expanded or discontinued after the trial period. 

About the project

Opioid use disorder (OUD) can be a chronic, recurrent condition that leads to morbidity and mortality. It is often treated with medication-assisted treatment (MAT).

The government has decided to introduce a 5-year pilot project with heroin-assisted treatment (HAB) in Oslo and Bergen to reach those with OUD who have not succeeded with MAT.

Our research group consists of experienced national and international researchers who will evaluate the HAB pilot project through a coordinated and broad research approach incorporating both clinics and user organizations.

Our evaluation will focus on patients' overall health and quality of life and on the efficacy of HAB in Norway.


Our goal is to evaluate HAB by examining patients' physical and mental health, the factors that affect their quality of life and other changes over time.
We will use qualitative and quantitative methods to investigate such questions as:

  • Can HAB be integrated into the Norwegian system?
  • Is HAB feasible and acceptable for patients and for staff in drug-assisted rehabilitation?
  • What are the costs and benefits of HAB in a Nordic context?

The research project’s resulting evaluation will be published as a report to the Norwegian Directorate of Health and will include a recommendation for possible continuation of HAB.
